Long–term results of self–expandable stent implantation to chronic total occlusion (CTO) in superficial femoral artery (SFA) of TASC (TransAtlantic Inter–Society Consensus) D remains unknown.
From 2004 to 2011, self–expandable stent implantation to CTO in SFA of TASC D was performed successfully in 72 lesions in 68 patients. Long–term results were examined in these patients. Cox–proportional hazard model was used to evaluate the predictor of restenosis. In uni–variate model, factors with P–value less than 0.2 were included in multivariate models as co–variate.
Mean follow–up period was 38.8±25.6 months. Patients with hemodialysis (HD) and diabetes were included in 20.6% and 51.5%, respectively. Mean occlusion length was 244.6±34.1mm. Basically, procedure was performed using 0.014 or 0.018 inch wire. Bi–directional approach was performed in 69.4%. Primary and secondary patency was shown as Kaplan–Meier curve in figure. In uni–variate model, HD and administration of ACE/ARB were factors with P–value less than 0.2. Hazard ratio (HR) of these factors in multi–vatiate model were as follows (HD; HR 2.778, 95% CI 1.223–6.313, P=0.015, administration ACE/ARB; HR 1.980, 95% CI 0.823–4.760, P=0.127).
Long–term patency of self–expandable stent implantation to CTO in SFA of TASC D was acceptable. Only HD was independent predictor for restenosis.
